Unlock all Genetics.
Full Cast achievement quick answer
Full Cast unlocks after all 21 current Genetics are available. Version 1.2 fixed an older trigger bug that only checked the condition at the end of regular Pressure runs.
On Version 1.2 or newer, finishing the run that reveals the last Genetic should trigger the check even when the unlock happened in a Challenge, Extinction, or Exploration run.
If the Codex shows 21/21 but the achievement still does not appear, finish the current run, confirm the live version, restart once, and then use the in-game BugReport route instead of editing the save.
